3a diseases headlines Flashcards
Bishop Scoring
Rates the favourability of the cervix (10 is good). Based on dilatation, position in vagina, effacement
Partogram
Measures progress in labour.
- dilatation of cervix
- vital signs
- liquor colour
- Fetal heart rate
Cardiotocography
Measures FHR and uterine contactions (you expect variability and accelerations), FHR 110-160, no decelerations. Not useful antenatally unless daily in high risk
Fetal scalp samples
Amnioscope to get blood sample. pH below 7.2 needs delivery as acidotic and hypoxic
Amniocentesis
Fine gauge needle and US. (15 weeks) Chromosomal abnormalities, CMV and toxoplasmosis, Sickle cell, CF and Thallasaemia. 1% miscarry
Chorionic villus sampling
Biopsy of trophoblast. (11 weeks (quicker)) Higher miscarriage rates than amniocentesis. PCR and FISH for results.
Sperm sample boundaries of viability
5-15 million/mL=oligospermia
<32% motile= asthenospermia
Causes of male subfertility
Idiopathic Drug exposure (alcohol, smoking, steroids) Varicocele Antisperm antibodies Infections Kleinfelters CF Kallmans TURP
APGAR score
HR RR Muscle tone Colour Reflex /10. At 1 and 5mins. Resuscitation? Neuro outcome?
Assisted conception
Intrauterine insemination (IUI) if mild sperm problems. Intracytoplasmic sperm injection (ICSI) if severe.
IVF -mulitple follicular development -ovulation and egg collection -fertilisation and culture -embryo transfer. Multiple pregnancy and ovary overstimulation risks
Combined oral contraceptives
Exert negative feedback on gonadotrophin release, inhibiting ovulation. Thin endometrium and thicken cervical plug. Withdrawal bleeds if 1 week break, if not then spotting
Progesterone side effects
Depression Bleeding Amenorrhoea Acne Breast discomfort Weight gain Reduced libido
Oestrogen side effects
Nausea Headaches Increased mucus Fluid retention and weight gain Breast tenderness and fullness Bleeding
Hormonal contraceptive negatives
Major complications (venous thrombosis, venous thromboembolism, migraine, stroke) Minor side effects
Depoprovera
IM injection every 3 months, reduced bone density. Progesterone
Emergency contraception
IUD
Morning after pill
Barrier contraceptives
Male condom Female condom Diaphragms Caps Spermicides
What is the difference between IUDs and IUSs
IUD copper- toxic to sperm
IUS(system)- mirena (progestogen) hormonal.
General advantages and disadvantages
User dependence
Complications
Contraceptive
Protects from STIs
Other contraceptives
Male and female sterilisation
Pneumonia
Fever, tachypnoea, malaise, RDS.
CXR, O2 sats
Amoxicillin
Pneumococcus, mycoplasma, haemophilus, staphylococcus, TB, viral
Croup
Viral laryngotracheobronchitis
6 months to 6 years (2yo)
Upper airway obstruction (=stridor, barking cough, hoarse)
Pred
Epiglottitis
Caused by H. influenza B so went down cos of vaccine. Very acute, no preceding symptoms. Silent. Cant drink. Drooling. Soft stridor
Asthma
Inflammation, hyperresponsiveness, narrowing
Wheeze, cough, breathless, chest tight
Worse at night, triggers, symptoms between exacerbations
Peak flow diary, sleep? exercise?
Salbutamol (ipratropium bromide if young)
Salmeterol
